What is the perimeter of the triangle?

36 units

Step-by-step explanation:

The short leg is 9 units and the long one is 12 units.

Use pythagorean theorem to find the hypotenuse, a² + b² = c²

Plug in the numbers: 9² + 12² = c²

81 + 144 = c²

225 = c²

√225 = c

15 = c

Find perimeter by adding all 3 sides: 9 + 12 + 15 = 36 units.

C). Symbolism

Explanation:

Symbolism is demonstrated as the literary device in which the author uses an object, place, word, etc. as symbols to convey a deeper idea or thought. It assists the author to represent the complex ideas or concepts through these symbols more effectively. The symbols are attached with a meaning much deeper and significant than the literal meaning. Thus, the bold phrase in the given sentence i.e. 'figurative language' could be replaced with 'symbolism' to make the vocabulary more precise and specific. The word 'symbolism' more efficiently justifies the definition 'to communicate complex concepts'. Thus, option C is the correct answer.
